This paper proposes a highly accurate rotor position estimation method based on deadbeat predictive control and sensorless control using current derivative values. Compared with PI control, deadbeat ...

This involves continuous monitoring of the rotor’s angular position using position sensors such as encoders or resolvers. If the measured angle deviates from the expected value, indicating a potential ...

What you'll learn: Other available options for permanent-magnet motors that use rare-earth materials. What is an EESM? Tula's DMD alternative to achieve EV powertrain efficiency.

In this article, the sliding mode observer (SMO) is used to estimate the back EMF of the motor. The basic principle is to estimate the back EMF e α, e β of the PMSM by using the SMO, then filter the ...

Therefore, propose horizontal well tractor PMSM sine wave drive technology. The paper discusses the mathematical model of permanent magnet synchronous motor, analyzes the working principle of ... Xu, ...

For the detection of rotor position in Permanent Magnet Synchronous Motor (PMSM), this paper presents an improved estimation method with switch-Hall-effect sens A PMSM rotor position estimation with ...

And also a stator resistance variation can induce a performance degradation of the system. Thus a sixth-order Discrete-time Extended Kalman Filter approach is proposed for on-line estimation of speed, ...
